Effects of poultry offal meal and soyabean meal mixtures on the performance and carcass quality of broiler chicks

Abstract

An experiment was conducted to test four different mixing ratios of soyabean meal (SBM) and poultry offal meal (POM) on the performance, histology and carcass evaluation of broiler chicks. The mixing ratios used in this study were (POM and SBM) 25:75, 50:50, 75:25, and 100:0. The experiment was conducted for 8 weeks. Feed intake significantly increased as the proportion of (POM) increased up to 25%. Beyond this level, additional POM did not result in corresponding feed intake for the bird. Body weight gain varied positively with increasing POM proportion in the mixture and followed similar trend recorded for feed intake. Birds fed with 25% (POM) recorded the highest values 79.20g/bird/day and 37.7g/bird/day, respectively for feed intake and weight gain. The lowest feed intake and body weight gain values were observed for birds fed diets containing the highest POM proportion (75%). These values were 59.72g/bird/day and 22.22g/bird/day respectively. Feed conversion ratio was significantly affected (P
